[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 7This utility model provides a technical solution: a SIM card tray detection device, including a workbench 1. Two support plates 2 are fixedly connected to the top of the workbench 1. Two rotating rollers 4 are rotatably connected between the two support plates 2. A conveyor belt 5 is arranged on the outer side of the two rotating rollers 4. Multiple fixed seats 7 are equidistantly fixedly connected to the outer side of the conveyor belt 5. A rotating shaft 8 is rotatably connected inside each of the multiple fixed seats 7. An electromagnet 9 is fixedly connected to one side of the rotating shaft 8. A magnet 10 is slidably connected to the inner side of the rotating shaft 8. Two connecting rods 11 are fixedly connected to the side of the magnet 10 away from the electromagnet 9. A clamping seat 12 is fixedly connected to one end of each connecting rod 11. A first spring 13 is fixedly connected between the side of the magnet 10 near the connecting rod 11 and the side inside the rotating shaft 8. The first spring 13 is located on the outer side of the connecting rod 11. A tactile switch 23 is fixedly connected to one side of the rotating shaft 8. A gear ring 22 is fixedly connected to the outer side of the rotating shaft 8. Two contact rods 6 are fixedly connected to one side of the support plate 2. A rack 2 is fixedly connected to one side of the support plate 2. 4. By setting up a fixed base 7, a rotating shaft 8, an electromagnet 9, a magnet 10, a connecting rod 11, a clamping base 12, a first spring 13, a tactile switch 23, a gear ring 22, a contact rod 6, and a rack 24, after the fixed base 7 moves to the clamping position, the tactile switch 23 is triggered to control the electromagnet 9 to be energized, thereby causing the tactile switch 23 to generate a repulsive force on the magnet 10. This compresses the first spring 13 and drives the clamping base 12 to complete the clamping of the SIM card tray. This facilitates inspection when transporting the SIM card tray. Furthermore, through the cooperation of the gear ring 22 and the rack 24, the final length of the rack 24 can rotate the gear ring 22 by 180 degrees, thus completing the flipping process of the SIM card tray. This allows for double-sided inspection of the SIM card tray without manual intervention, ultimately eliminating the need for manual intervention, reducing the workload of workers, and ensuring inspection efficiency and accuracy through double-sided inspection, thereby improving the production yield of SIM card trays.

[0022] A support frame 25 is fixedly connected to the top of the workbench 1. A cylinder 26 is fixedly connected to the inner side of the support frame 25. A lifting plate 28 is fixedly connected to the output end of the cylinder 26. Two vision inspection devices 29 are fixedly connected to the bottom of the lifting plate 28, which makes it easy to push the vision inspection devices 29 to the required working position and then inspect the SIM card tray.

[0023] Two limiting telescopic rods 27 are fixedly connected to the inner side of the support frame 25. The telescopic ends of the two limiting telescopic rods 27 are fixedly connected to the top of the lifting plate 28, which can guide and limit the movement of the lifting plate 28.

[0024] A first fixing ring 14 is fixedly connected to one side of the fixing base 7, and a second fixing ring 15 is fixedly connected to the outer side of the rotating shaft 8. A first sliding groove 16 is opened inside the second fixing ring 15. A first slider 17 is slidably connected to the inner wall of the first sliding groove 16. Two first fixing rods 18 are fixedly connected to one side of the first slider 17. A corner block 19 is fixedly connected to the end of the first fixing rod 18 away from the first slider 17. The outer side of the first fixing rod 18 is located on one side of the first slider 17 and is fitted with a second spring 20. A plurality of positioning corner grooves 21 that cooperate with the corner block 19 are opened circumferentially at equal intervals inside the first fixing ring 14. The position can be limited when the SIM card tray is flipped for detection, thus ensuring the stability of the position during detection.

[0025] The electromagnet 9 and the magnet 10 have the same magnetic poles on their opposite sides. When the electromagnet 9 is energized, it can generate a repulsive force on the magnet 10, thereby clamping and fixing the SIM card tray.

[0026] One of the support plates 2 is fixedly connected to a motor 3 on one side. The output end of the motor 3 is fixedly connected to one of the rotating rollers 4, which facilitates the conveying and detection of the SIM card tray.

[0027] Specifically, during testing, the control cylinder 26 pushes the lifting plate 28 downward, and the lifting plate 28 is guided and limited by the limiting telescopic rod 27. Two vision inspection devices 29 can cooperate to perform double-sided inspection of the SIM card tray. The control motor 3 rotates one of the rotating rollers 4, so that one rotating roller 4 can drive the other rotating roller 4 via the conveyor belt 5. When the fixed seat 7 on the conveyor belt 5 moves to the contact rod 6 near the end of the motor 3, the contact rod 6 triggers the tactile switch 23. The tactile switch 23 controls the electromagnet 9 to be energized, so that the energized electromagnet 9 generates a repulsive force on the magnet 10. The moving magnet 10 compresses the first spring 13, and drives the clamping seat 12 via the connecting rod 11. The two adjacent clamping seats 12 can clamp the SIM card tray. When the clamped SIM card tray moves under the first vision inspection device 29, one side of the SIM card tray can be inspected. When the fixed base 7 continues to move, the gear ring 22 can contact the rack 24. The length of the rack 24 is designed to correspond to the position of the tactile switch 23 when it is flipped 180 degrees. In this way, the tactile switch 23 can be flipped by the rack 24. The tactile switch 23 can drive the internal rotating shaft 8 to rotate in the fixed base 7, so that the two clamping seats 12 holding the SIM card trays can be flipped 180 degrees. When the rotating shaft 8 rotates, it can drive the outer second fixing ring 15, so that the corner block 19 in the second fixing ring 15 moves outside the first fixing ring 14. The moving corner block 19 drives the first slider 17 through the two first fixing rods 18, so that the first slider 17 slides and compresses the second spring 20 in the first slide groove 16. The second spring 20 generates a reset repulsive force on the first slider 17, which can limit the position of the clamping seat 12 holding the SIM card trays to ensure the stability of the position during detection.
